Among the cellulases by Celludomonas sp. KL-6. CMCase and filter paperase, which were produced as the out enzymes of cell, had been much produced, but very small amounts of β-glucosidase, the enzyme of which is cell bound form, was produced by this organism. The optimal culture times for CMCase and filter paperase productions were 5 days, while that of β-glucosidase was 4 days. When this strain was cultured under the optimal medium for enzyme production, CMCase, FPase and β-glucosidase were 82 units/㎖. 80 units/㎖ and 1.2 units/㎖, respectively. Thus these results were showed to increase enzyme productivities as about 60∼70% than those produced in basal medium. CaCO₃ injected to the medium as the ratio of 0.1% was not only enhanced cellulase activities but also effective as acid neutralizing agent. The production effects of lignase and lactase by this bacterium in filter paper medium was not appeared.
